A. rhomheum is distinguished at once by the verj' high dorsal and 

 anal fins. The dorsal has a greater number of ra^^s, and the body is a 

 little deeper than that of the other species. There is a rather indis- 

 tinct dark spot at the upper part of the gill-opening and a dark band 

 on the posterior half of the body; the band originating below the 

 insertion of the dorsal, on the row of scales above that l)earing the 

 lateral line, growing wider and extending posteriorly to where it 

 abruptly ends on the caudal peduncle, falling short of the base of the 

 caudal fin a distance about equal to the diameter of the pupil. Above 

 the lateral band the body is dark colored; below it is light. On the 

 dorsal is an indistinct light band extending the length of the fin just 

 below the middle of the ra^s. The anal has a similar band. 



^The collection contains three species of Acheilognathus, which we identify as A. 

 rhomheum, A. lanceolatum, and ^4. intermedium. A table of measureinents is given 

 for comparison.
